Double Bubble is a comedy show like no other. It showcases the brightest upcoming talent on the circuit but the twist is that the audience can have judge the acts after their set.
Each act gets 5 minutes on stage and each audience member gets 2 cards. The green card is a plus vote, the red card is a minus. At the end of the set, if an audience member likes your set they can hold up their green card to vote you through to the final. Similarly, if they didn't enjoy it, they can hold up the red card. The acts with the net most plus votes will get through, where a winner is decided.
